Description

Technical Field

[0001] The utility model relates to the technical field of cigarette production equipment, in particular to an annular guide rail mechanism of a packaging machine. Background Art

[0002] The small box transparent paper packaging machine wraps and scalds the small box cigarette packs with transparent paper, so that the transparent paper can wrap the cigarette packs well and play a moisture-proof role. The packaging machine outlet transports the packaged cigarette packs to the downstream and scalds the side seals on the circular conveyor belt.

[0003] At present, the small-box transparent paper produced by the ZB45 packaging unit commonly used in the tobacco industry has a large number of quality defects such as side seal wrinkles, bubbles, and dead folds, and does not meet the quality requirements of smoothness and flatness; in the past, due to the lack of a better solution, the uneven side seal quality defects of small-pack transparent paper produced by ZB45 were common in the industry. Through scientific and technological research, the applicant added three side cover hot stampings, and performed two low-temperature hot stampings on the corresponding side transparent paper, so that the two sides of the cigarette pack are smooth and flat, which can greatly improve the appearance quality of small-pack transparent paper cigarette packs. However, in such a process, it is necessary to use a conveyor belt to intermittently transport small boxes of cigarettes to the designated hot stamping position; and the time of transporting to the hot stamping position must be highly synchronized with the rhythm of other equipment. If there is a time difference, it will affect the side seal hot stamping quality of the cigarette pack.

[0004] There are many solutions in the prior art for intermittently conveying cigarette packs on a conveyor belt. For example, the most common one is to use a servo motor to control the intermittent rotation of the conveyor belt, so as to achieve the purpose of intermittently conveying the cigarette packs. However, when the cigarette packs are intermittently conveyed in this way, the conveyor belt is relatively soft and is affected by inertia. When the cigarette packs are conveyed on the conveyor belt through the mold box rack, large shaking and noise will be generated. Utility Model Content

[0024] like Figure 1-4As shown, an annular guide rail mechanism of a packaging machine of the utility model comprises a frame of the packaging machine and an annular guide rail arranged on the frame, the annular guide rail is composed of two semicircular arc guide rails 108 and two linear guide rails 107, a slide 104 is slidably connected to the annular guide rail, and inwardly recessed flat-bottomed V-shaped slide grooves are symmetrically arranged on the left and right sides of the annular guide rail, two rollers 115 are respectively arranged on both sides of the annular guide rail at the bottom of the slide 104, and the outer circle of the roller 115 is also V-shaped opposite thereto, and the roller 115 is slidably embedded in the slide groove to limit the vertical direction of the slide 104, and this V-shaped structure makes the contact surface between the roller 115 and the annular guide rail large, can withstand a large load, and at the same time can ensure high running accuracy and small running resistance. Mold boxes 106 are provided at both ends of the top of the slide 104, and the cigarette packs can be positioned in the mold boxes 106. An annular conveyor belt is provided on the inner side of the annular guide rail. The annular conveyor belt is installed on the frame and is used to drive the slide 104 to intermittently move along the annular guide rail.

[0025] A straight pin 114 is provided on the inner side of the annular guide rail at the bottom of the slide 104, and an eccentric pin 112 is provided on the outer side of the annular guide rail. Figure 2 As shown, the left side is the outer side of the slide 104, and the right side is the outer side of the slide 104. The slide 104 has mounting holes on both sides of the bottom, and connecting holes on both sides of the top corresponding to the mounting holes. The mounting holes are connected to the corresponding connecting holes. The top of the straight pin 114 can be rotatably inserted into the mounting hole on the right side of the slide 104. A countersunk bolt 117 is provided between the straight pin 114 and the slide 104. A threaded hole for inserting the countersunk bolt 117 is provided on the top of the straight pin 114. The bottom end of the countersunk bolt 117 passes through the connecting hole and the threaded hole in turn to connect and fix the straight pin 114 and the slide 104. The roller 115 on the right side of the slide 104 is coaxially rotatably installed at the bottom of the straight pin 112 through a bearing. The eccentric pin 112 includes an upper half and a lower half. The upper half can be rotatably inserted into the mounting hole on the left side of the slide 104. A countersunk bolt 117 is also arranged between the upper half of the eccentric pin 112 and the slide 104. The connection method is the same as that of the right straight pin 114. The lower half is integrally formed with the upper half, and the lower half is eccentrically arranged at the bottom of the upper half. The roller 115 on the left side of the slide 104 is coaxially rotatably installed on the lower half through a bearing.

[0026] The slide 104 is also provided with a locking screw 113 for limiting the rotation of the eccentric pin 112. In this embodiment, a threaded hole is provided on the left wall of the slide 104, and the threaded hole is connected to the left mounting hole of the slide 104. Two locking screws 113 are provided in the threaded hole, and the locking screw 113 located inside abuts against the upper half of the eccentric pin 112 to prevent the eccentric pin 112 from rotating.

[0027] In the above embodiment, a mounting nut 116 is further provided between each roller 115 and the bottom of the slide 104. The mounting nut 116 is threadedly connected to the upper half section / straight pin surface of the eccentric pin 112. The upper surface of the mounting nut 116 abuts against the bottom of the slide 104, so that the eccentric pin 112 / straight pin 114 is stably installed and securely connected. By loosening the locking screw 113 and rotating the left countersunk bolt 117, the eccentric pin 112 and the left roller 115 can be driven to rotate, so that the gap between the roller 115 and the annular guide rail can be adjusted, so that the slide 104 can be loaded after being installed on the annular guide rail, but not too tight, so that it can slide easily on the guide rail, with a simple structure, low cost, and convenient adjustment.

[0028] The annular conveyor belt includes a driving wheel 100 and a driven wheel 109 horizontally mounted on the frame. The driving wheel 100 and the driven wheel 109 are sleeved with a synchronous belt 102. The driving wheel 100 and the driven wheel 109 are respectively arranged on the inner side of two semicircular arc guide rails 108. The shape of the synchronous belt 102 after tensioning matches the annular guide rail. Several push blocks 103 are arranged at equal intervals on the synchronous belt 102. A rotating rod 105 cooperating with the push block 103 is rotatably mounted on the slide 104. The push block 103 is fixedly mounted on the synchronous belt 102 by screws. A groove is arranged on the outer side of the push block 103. The rotating rod 105 is rotatably embedded in the groove of the push block 103. The groove of the push block 103 pushes the roller 115 on the slide 104 to drive the slide 104 to move, so that the slide 104 will not shake or make noise when it moves intermittently during the transportation of cigarette packages. A limit block 101 is provided on the inner side of the synchronous belt 102 to prevent the synchronous belt 102 from loosening.
